Access Violation on connect

[Patrick]

Hello. I have the following problem using dbexpsda.dll (file version 2.50.7.0) in Delphi 7, MDAC 2.8 SP1 on WinXP SP2. When I set the connected property of a TSQLConnection component to true at design time the connection works OK. When I do it at run time I get an AV. I can use dbexpmss.dll without error.

Most possible you have two dbexpsda.dll files - first (right) in Windows/System folder and second in your project folder. Try to search for all such files on your HDD.

I have a very similar problem.

I create the TSQLConnection dynamically and call the Open method.
Running the compiled program is fine, but I get an AV (attempt write to address 0) when I run under the Delphi7 debug mode.

The error occurs during the Kernel function LoadLibrary, I only have one version of dbexpsda.dll

Please supply us following information.
- Version of Delphi
- Version of DbxSda. You can find it in history.html or in DLL version info

Do you use DbxSda Std or Trial?

I have rebuilt the DLL and problem seems to have gone away. Must have been some glitch on my system.

Sorry to trouble you.
